The HESA Shahed 278 (Persian: شاهد ۲۷۸) is an Iranian-made light utility helicopter.

The first platform was the Shahed-278 (Oh-78), described as a light reconnaissance helicopter, armed with weapons and sensors.

It is a four-seater; intended for dual military/civil use, though designed primarily to meet military requirements.

It was designed entirely in Iran, according to the manufacturer, although some sources report use of locally made airframe and dynamic components of the Bell 206 JetRanger.
